Domestic cat

The following is from "The Current Affairs Field Guide to Socialist Animals" by Lyta Gold and Nick Sirotich:

When not confined to an artificial, atomized environment such as a house or apartment, cats naturally form complex, mutually co-responsible colonies. Individuals retain highly independent and even snobbish behaviors, often leading to factionalism within the colony, or even full-blown schisms. Additionally, cats belong to the labor-reductivist behavioral niche: once basic bodily needs have been met, the domestic cat shows little interest in empty work for work’s sake. </blockqoute>

The black cat is a common symbol of the Industrial Workers of the World, anarcho-syndicalism, and wildcat strikes.
